Studies have shown that blocking substance P (SP) binding to neurokinin 1 receptor with spantide I prevents Pseudomonas aeruginosa-induced corneal perforation in susceptible C57BL/6 mice. This study tested the effect of SP injection on the resistance response (cornea heals) of

Apoptosis was examined after Pseudomonas aeruginosa corneal infection in C57BL/6 (B6, susceptible) and BALB/c (resistant) mice. TUNEL staining, real-time RT-PCR, polymorphonuclear neutrophils (PMNs) and macrophage (Mphi) depletion, and immunostaining were used. Intense TUNEL staining was seen in BALB/c versus B6

The dorsal periaqueductal gray (dPAG) is the main output structure for the defensive response to proximal aversive stimulation. Panic-like responses, such as freezing and escape behaviors, often result when this structure is electrically stimulated. Freezing also ensues after termination of

Bacillus anthracis edema toxin (ET), composed of protective antigen and an adenylate cyclase edema factor (EF), elicits edema in host tissues, but the target cells and events leading from EF-mediated cyclic-AMP production to edema are unknown. We evaluated the direct

Acute cutaneous neurogenic inflammation initiated by activation of transient receptor potential vanilloid-1 (TRPV1) receptors following intradermal injection of capsaicin is mediated mainly by dorsal root reflexes (DRRs). Inflammatory neuropeptides are suggested to be released from primary afferent nociceptors participating in
